down from the stove and chimney so that the soot may be shaken out of the pipes. This entails considerable inconvenience and the worh itself is often quite difficult and dirty.

It is the primary object of this invention,

suitable cleaning attachment for ordinary stove pipe joints or sections, which may be adjustably mounted within the pipe, with one end extended ou wardly, so that the said attachment or leaner may be readily manipulated for the purpose of cleaning the pipe without the said pipe being taken down.

further object is produce such device in a simple, practical and efiicient form, readily attachable to any stove pipe.

In the drawings, Figure 1 represents a vertical, longitudinal section of a stove pipe joint, showing clean r located within the same.

ig. 2 is a similar view of a lower joint, flared at the bottom for attachment to the pipe flange of the stove.

Fig. 3 is a vertical, longitudinal section taken on the line E l-ll in Fig. 1.

Fig. i is a vertical, longitudinal section showing an adaptation of the device as mounted in an elbow joint.

Ref rring more particularly to the drawings, in carrying out my invention in its preferred form of construction, I take anordinary joint or section of stove pipe as l andcut medially a transverse hole or slot 2 therein. The wall of the pipe is then creased outwardly as shown at 3 along a longitudinal line immediately below this slot 2, to form a protruding crease or convex guide-way 4: to partially receive the outer longitudinal shaft 5, formed from and at the upper end of the bar 9, and adapted to reciprocate along and within said guide way at. The shaft 5 may be bent at its outer Specification of Letters Patent.

end to form a handle 6. An upper auxiliary guide-way 7 is creased concavely inwardly along alongitudinal line immediately above and in alinement with the lower, outwardly convexed crease 3, thus the two guide-ways and 7, the one convexed and the other concaved, in combination are adapted to enbrace the shaft 5, and permit same freely to slide back and forth therein. The cleaner itself, including the outer shaft 5 and the inner scraping rings to be hereinafter described, are formed from a single heavy wire or small bar of iron, represented at 9. The outer end of this wire or bar 9 forms the shaft 5, as aforesaid. At the lower portion of the shaft 5, at the point 8 the wire 9 is bent laterally and thence is formed into a lower scrapingring 10, same passing around the inner surface of the pipe. At the point 11, where said ring completes its circuit, the wire 9 is bent at a right angle upwardly, forming the inner, longitudinal shaft 12. At the point 13 the bar 9 is again bent at a right angle and again extended around inside the pipe to form the upper soot-ring 14, said ring ending at the point 15 after completion of its circuit. Thus there is formed inside the pipe 1 an upper ring i l and a lower ring 10, connected by a vertical link or shaft 12, the entire device depending from and being controlled by the outwardly extended shaft 5 endin in the handle 6. It is evident that by moving the handle 6 up and down the scraping-rings 14: and 10 are likewise passed up and down along the inside of the pipe 1 and across the inner surface thereof, thus breaking loose any soot which may have collected upon said inner surface. Said soot when so broken loose either falls into the stove and is burned, or is carried out through the flue by the draft.

\Vhile I have herein described a certain specific method of constructing and assembling the elements of my invention, it is understood same may be varied in minor details, not departing from the spirit of my invention as defined in the appended claim.

WVhat I claim to be new and patentable is:

In combination with a stove pipe having an aperture leading to the interior thereof,

and a longitudinal guide-way extending along the pipe wall formed by creasing the pipe wall at one side of the aperture concavely outwardly and the pipe wall at the other Side of the aperture concavely inthe outer end portion of the wire shaft along wardlyya cleaning elementfomned by,-;8X.1 saidguideway to form a handle for ma- 7 tending a shaft of heavy Wire through the nipulating theinner soot scraping rings.
